Metal Gear Solid is known as one of the greatest franchises in gaming history and for good reason. The HD Collection is a great way to be introduced to the series, or to rekindle old memories in a higher resolution. A couple of the games are, however, quite old and are subject to some quirky control schemes which can be jarring for more recent gamers. Each game in the pack is masterfully crafted, with great stories and great stealth action. Though it contains the first two Metal Gear games from the 80's, Metal Gear Solid 1 was unfortunately left out. While it is not essential to the experience, it is a great game and unfortunately is not available on the Xbox 360. The same goes with Metal Gear Solid 4, the latest episode in the story, which is exclusive to PS3. This means that if someone is looking for more MGS action, they'll need to acquire other platforms, which can be both costly and frustrating.
Overall, if you're looking to buy this game and have a PS3, buy it on that. Otherwise, this is your best shot.
